Pros

“Clean interface, easy setup, flexible list and data management, scalable for larger sends, usable template builder”

Martina S.

“The ability to quickly and easily integrate the corporate marketing platform into SendGrid to enable campaigns and help ensure message delivery.”

Shane S.

CEO

“SendGrid offers robust API support, which makes it easy for developers to integrate email sending into applications.”

Himanshu V.

Senior software developer

Pros

“Postmark’s pricing is on the higher end compared to other email service providers”

Himanshu V.

Senior Software Developer

“The documentation feels a little fragmented - some things are in the official API documentation, while other things missing from the official documentation are included in blog posts or other posts within the Support Center.”

Gregor S.

Director

“Have a not find any difficulty yet, but have receive an email that from July onwards they will switch the subscription to montly basis instead of anually, that too also comes after active campaign group take over the postmark app”

Bhagya M.

Editor

Cons

“The pricing levels are not worth the money because our e-commerce traffic is at its peak, and customer service is painfully slow when we have urgent account problems or some data management failures.”

Amir H.

E-Commerce Manager

“I’ve run into bugs that the support team hasn’t been able to help with and often feel limited by the automation capabilities.”

Hayley A.

Marketing Manager

“Free Plan have strict limit for number of mail you can send, that make difficult for upgrade without testing it proper.”

Tarun S.

Web developer

Cons

“I have lost so many emails due to sneaky changes in their pricing tier without proper notice and extremely poor customer service. While they used to care about the customer most than anything, they've now become soulless, uncaring and unapologetic.”

Vadim K.

Owner

“Pricing was a concern at first but well... If we have to pay for a 3rd party provider to deliver our e-mails, we'd rather spend a bit more and have e-mails inboxed rather than discarded or sent to spam. Plus, if you run in any issue, Postmark support usually answers warmly under 24 hours... where the competition usually takes either forever or/and a very cold and super technical approach making you feel like an idiot.”

Geoffrey G.

Founder

“I was a bit frustrated : most SMTP integrations wouldn't work with their initial implementation of marketing emails, as it required to send custom headers along the e-mail. But they took the feedback and a few months later, a workaround was implemented.”
